Nowadays in this modern era many inventions are invented in many aspects like in education, transportation, and technology to make the human life more easier. For example in transportation, nowadays everyone can go around the world by using plane even if the distance between the countries is really far. Internet is the one example of the invention in education aspect and e-book is the other invention in education aspect. What is invention? Invention is a new idea or creating new items. So, modern invention is a new idea or new items that found in this modern era. Every invention has their own function but not all invention give an advantage.
Some invention has an disadvantage too and some of them have both. In this paragraph I will explain 3 items that give advantages and 3 items that give disadvantages. First advantage item is hybrid car. hybrid car is a car that have two power sources (electric & fuel) to make the car or the vehicle move. Hybrid car highlight working concept is by using the batteries to make the motor give acceleration to the engine so the engine use more less energy. The motor and the engine can be use to recharge the batteries by the motor act as the dynamo to recharge the batteries.
At low speed or idle the batteries gives all energy to make the car move so the engine is turn off and at the high speed the engine and the batteries give the energy so it give a powerful energy to move the car in the high speed. So, by using two power sources, the car use more less fuel and produce more less emissions too. So, this hybrid car has advantage to reduce the use of fuel. Because nowadays the amount of usage the fossil fuel every year are increase. So, if we did not reduce the usage one year we do not have any fuel sources. Example of hybrid car Toyota Prius, Honda crz, Honda Insight Hybrid, and etc.
The Essay on Diesel Engine Engines Fuel Combustion
INTERNAL-COMBUSTION ENGINE. When a fuel is burned in air, the resulting hot gas tries to expand, generating a force that can be used to move a piston in a cylinder, as in the automobile engine, or to drive the blades of a turbine. In either case, because the combustion takes place within it, the engine is called an internal-combustion engine. Modern transportation relies heavily upon internal- ...
Second advantage modern invention is internet. Internet is global system of interconnected computer network that use the standard Internet Protocol to access many information around the world. In this modern era Internet become very useful and helpful for human because with the internet they can access or find the information that they need. For example student now can access so many information that they need for they research or they study, or business man or woman now really need the internet to communicate with other business man or woman around the world to know the new information about the business without meet each other.
And now many banks are release the Internet banking so the customer of that bank can transfer money to other person by using the internet everywhere so the customer does not need to come to the bank to transfer some money. On the other internet can be an entertainment like you can play game with around the world by using the internet, listening to the music, watching video, and many more. And now Internet became a part of human lifestyle because internet gave many advantages for human. And the third item of the advantage in modern invention is ultrabook.
Ultrabook is a category of notebook, ultrabook is a notebook that have a thin design and lightweight notebook. This type of notebook is very portable beside of this type of notebook have thin design and less weight, ultrabook have a notebook specification like using notebook processor, big storage, higher RAM, and some of ultrabook have second VGA which mean this type of notebook have high performance and it is different with the netbook, netbook have smaller design and less weight too, but netbook does not using notebook specification so that netbook does not have high performance like notebook or ultrabook.

Users - connected to the net and interacting with it The communications lines and the communications equipment The intermediaries (e.g. the suppliers of on-line information or access ...
Some example of ultrabook is Asus Zenbook, HP Envy Spectre, Macbook Air, Acer Aspire S5, etc. So beside ultrabook is lighter and thinner than notebook, ultrabook have high performance like notebook and more portable than notebook. So ultrabook is very useful for business people who always bring notebook when travel even the students because is lighter and have elegant design. Modern inventions not only have advantages items but have some disadvantages items too.
And the first disadvantages item is internet. Internet not only have some advantages function but internet have some disadvantages too. The first disadvantages of internet are student or under 18 years old children can easily access porn. Maybe is not a problem when adult access the porn website but it is become a problem when children access a porn, because of they does not have a lesson about sex they curious to try sex so it can make the level of free sex is increase.
And because of some porn website are not free to access and need to pay some of the children steal his or him parent credit card to pay for it so they can access it. And the second disadvantages of internet are people can betting by using the internet. Nowadays many betting website are available in the internet, so people can easily bet by using the internet maybe at some country betting is not a problem, but the problem is when children below 18 years old betting by using they parent credit card and they get the credit card from steal it.
And now there are so many fake betting website so it really dangerous for people who like betting. Second disadvantages modern invention is Air-conditioner using CFC. Air-conditioner is a machine that can control the temperature of the air. And CFC (Freon) is the cooling agent by using Freon air temperature become more cooler so it is very useful when the weather is hot. But now the use of Freon is forbidden, because Freon can cause global warming by contribute ozone depletion.
CFC can contribute ozone depletion because CFC is a Chlorofluorocarbon so when CFC released into the atmosphere CFC will unbound into atom C and this atom C is bonding with O that come from ozone molecule (O3) so when atom C is bonding with O it will become CO and one molecule of the ozone will disappear and atoms C not only bonding 1 atom O but 2 atoms O so it will become CO2 and the ozone Molecule become atom O.
The Essay on Recovery And Recycling Ozone Cfcs Cfc
ChloroflourocarbonsChloroflourocarbons were discovered in the 1920's by Thomas Midgley, an organic chemist at General Motors Corporation. He was looking for inert, non-toxic, non-flammable compounds with low boiling points that could be used as refrigerants. He found what he was looking for in the form of two compounds: dichlorodifluoromethane (CFC-12) and (CFC-11). In both compounds, different ...
The effect by dissipation of ozone molecule is the ozone cannot filtering the UV rays from the Sun and if ozone does not filtering the UV rays it can cause earth temperature become higher and the UV rays can cause skin cancer and it is dangerous. So it is the reason why Air-con using CFC became a disadvantage item. And the third disadvantage modern invention item is car. Car is vehicle that using gasoline to make it move. Car has advantages and disadvantages and the disadvantage of the car is the gas that is outcome from the car.
The gas that came from the car can cause eye irritation, global warming and etc. because the gases that get from the combustion are toxic like CO, Co2, HC, NOx, and tec. This gases can cause global warming because CO will bonding the atom O from the ozone molecule that can destroy the ozone molecule so it can make the greenhouse effect. Greenhouse effect is the when the earth absorb the heat from the sun and the heat is keep inside the earth. So it can make the earth temperature become more hot and it can cause the other effect for the human like skin cancer and it is really dangerous.
Modern invention not only gave advantages for human like portable items, “Green” items, easy to use items, and even really helpful items for human works, like examples ultrabook, hybrid-car, internet, and etc. But on the other hand, modern invention has some disadvantages too like poisonous items, items that can cause Global Warming, like example air-con using CFC or Freon, internet, etc. Modern invention can be advantages items and can be disadvantages items. So, nothing is perfect even invention in the modern era.
